NAME
stringprep - API function
SYNOPSIS
#include <stringprep.h>
stringprep(3) * in, size_t maxlen, Stringprep_profile_flags flags,
const Stringprep_profile * profile);
ARGUMENTS
char * in input/ouput array with string to prepare.
size_t maxlen
maximum length of input/output array.
Stringprep_profile_flags flags
a Stringprep_profile_flags value, or 0.
const Stringprep_profile * profile
pointer to Stringprep_profile to use.
DESCRIPTION
Prepare the input zero terminated UTF-8 string according to the
stringprep profile, and write back the result to the input string.
Note that you must convert strings entered in the systems locale into
UTF-8 before using this function, see stringprep_locale_to_utf8().
Since the stringprep operation can expand the string, maxlen indicate
how large the buffer holding the string is. This function will not read
or write to characters outside that size.
The flags are one of Stringprep_profile_flags values, or 0.
The profile contain the Stringprep_profile instructions to perform.
Your application can define new profiles, possibly re-using the generic
stringprep tables that always will be part of the library, or use one of
the currently supported profiles.
Return value: Returns STRINGPREP_OK iff successful, or an error code.
